Yeah I was thinking the same thing too, after further research today it seems to be a condenser and not related to the issues I'm currently having. Bugger back to the drawing board. Hoping its something to do with the coil, been doing some research into the one I was sold and cant seem to find if it is designed to be used with an external resistor or not. Car won't even attempt to fire. Pulled a plug out and earthed it to the engine then turned car over and was visibly very weak. I bought the car as an abandoned project with everything completely stripped from the engine bay, with there not being too many 2.0L 280zx cars I can't find much info if I've set it up right.
